coppercoins Pillar of the Community United States 7629 Posts	Posted 02/24/2008 1:16 pm Very different processes used for very different things... clad - sheets of cold metal are squashed together in a sandwich using - oddly enough - explosives. All our modern dimes, quarters, and half dollars are clad. They have a copper core and layers of copper-nickel on both sides. plating - metal objects dunked into another metal in liquid form. The liquid metal coats the other metal and dries when pulled out of the 'bath'. Zinc cents are plated with 100% pure copper. electroplating - use of a chemical solution, two different metals, and an electric current. The current pulls molecules of metal off one and deposits them by attraction to the other metal. This method is the most common form of plating coins after they have left the minting process - by privateers. Cents plated in nickel tend to be common, but are not mint products as such. Main difference between this and plating is that plating involves the melting of metal and dunking other pieces into it...like chroming a bumper. Report this Post to the Staff

gbchaosmaster Valued Member United States 328 Posts	Posted 02/24/2008 6:03 pm Electroplating is also cheaper than plating. If somebody decides to make a gold-plated dime or something, the person is more likely to electroplate it, rather than buy a couple bars of gold to melt. Cladding is the reason that you see two different colors on the edge of a cupronickel-clad coin. Report this Post to the Staff
